Jean-Baptiste-Camille Corot, French, 1796-1875 – Mother and Child on a Beach Philadelphia Museum of Art

The picture has something of this: people, two, reclining, water, group, veil, river, recreation, woman, wear, man, three, child, interaction.
Perhaps it’s a painting of a woman in a yellow dress and a little girl in a brown dress sitting on a blanket in a field next to a body of water.
